人类和环境 Man and His Environment
Throughout history man has changed his physical environment in order to improve his way of life. With the tools of technology he has altered many physical features of the earth.
He has transformed woodlands and prairies into farms and made lakes and reserviors out of rivers for irrigation purposes or hydroelectric power. Man has also modified the face of the earth by draining marshes and cutting through mountains to build roads and railways. However, man‘s changes to the physical environment have not always had beneficial results. Today, pollution of the air and water is an increasing danger to the health of the planet. Each day thousands of tons of gases come out of the exhausts of motor vehicles. Smoke from factories pollutes the air of industrialized areas and the surrounding areas of the countryside. The pollution of water is equally harmful. The whole ecological balance of the sea is being changed and industrial wastes have already made many rivers lifeless. Now environmental protection is more pressing than ever before. As we know, massive destruction of environment has brought about negative effects and even poses a great threat to man‘s existence.
Indifference to these problems will mean committing suicide. Therefore, effective measures should be taken and laws passed to conserve environment. Otherwise,man is certain to suffer from the serious consequences caused by this lack of care for his living surroundings
纵观历史，人类改变了自己的自然环境，以改善自己的生活方式。随着技术的工具，他改变了地球的许多自然特征。
他将林地和草原改造成农田和河流湖泊和水库，用于灌溉和水力发电。人类还通过排水、穿过群山、修建公路和铁路来改造地球的表面。然而，人类对自然环境的改变并不总是有有益的结果。今天，空气和水的污染对地球的健康是一个越来越大的危险。每一天，成千上万吨废气机动车辆的排气管排出。工厂释放的烟雾污染了工业区的空气和周围乡村。水的污染是同样有害的'。海洋的整个生态平衡正在改变，工业废物已经使许多河流没有生命。现在的环境保护比以往任何时候都更加紧迫。正如我们所知道的，大规模的破坏环境带来了负面影响，甚至对人类的生存造成了巨大的威胁。
对这些问题漠不关心将意味着自杀。因此，必须采取有效的措施，并通过法律保护环境。否则，人一定会遭受这种缺乏对他的生活环境的关心所造成的严重后果。
